WASHINGTON — And you thought “Back to the Future II” was just a movie.

Wednesday is Back to the Future Day — Oct. 21, 2015, is the day Doc Brown, Marty McFly and Jennifer Parker arrived from 1985 to set the plot of the second of the film series in motion. And in honor of the event, Doc Brown has taken to Facebook.
